A quick check for epistemic hygiene of a belief system:

In this belief system, is doubt generative or evil?

If it's considered evil, watch out, because the belief system is self-totalizing.

If it's considered generative, then even if the belief system is powerful, it is likely because it can absorb and grow from disconfirming evidence.

The former is a (dangerous) gilded turd.

The latter is a sublime jumble.

Another way of putting it: is the belief system open or closed?
